Typomorphic Characteristics of Pyrite of the No. 5 Ore Body in the Shuangwang Gold Deposit, Shanxi Province
摘要
Abstract
The Shuangwang gold deposit,located in Devonian stratum of the West Qinling, Shanxi Province, is a low-grade large breccia-type gold deposit. The typomorphic characteristics of pyrite ,which is the main gold-beating mineral, are studied in detail in this paper. The main crystal forms of pyrite are the { 111} and { hk0}, which accounts for 75 %. While the crystal form of 11001 is 25 %. The diagram of crystal form values exhibit the gold potential- ity increasing from east to west,with the trend extending to the west of exploration line No. 79. The thermoelectric coefficients of the pyrites range from - 250 to 250μV/℃. The thermoelectric conductive type of pyrites is mainly N-P type with the characteristics of N type and P type. The P type increases at the low part of the west ore body. The head halo elements Sb and Ba first decreases and then increases from up to down, and appears significant head halo inversion between exploration lines Nos. 71-75, with the enrichment trend on the west of exploration line No. 79. From upper to lower, near-ore halo ele- ments Cu, Pb, and Zn have enrichment trend under the exploration line No. 75 and in the west of exploration line 79. Rear halo element Bi enriches from upper to lower, with significantly high of the near-ore halo element Pb between the exploration lines Nos. 57-65, indicating that KT5 is close to the bottom of mineralization in this interval. High content of rear elements Mo and Co and coexisting with head halo elements between the exploration lines Nos. 73- 77 show that there may exist blind ore bodies at depth.关键词
